docs: generate each subsystem's cordis surface into its own page; delete the flat catalogs

Rebuild of the region machinery (PR3) on the post-#904 Typert projection:
renderPageRegion/renderInheritedPage live in dsh-typert-generator beside the
projection; scripts/gen-cordis-catalog.ts owns the curated SERVICE_PAGE /
EVENT_SCOPE_PAGE / SERVICE_WALK_EXEMPTIONS / LINK_MAP partition (fail-loud in
both directions, with the independent Context-merge scan backstopping the
projection's blind spot), spliceRegion, and the guarded pair auto-record.
docs/cordis-catalog/ is deleted: the flat events/services catalogs dissolve
into per-page regions and docs/cordis-catalog/core moves to docs/cordis-api/
with the inherited tier as its own generated page. The partition absorbs the
post-regrouping surface: ctx.typert → invariants.md, ctx.directoryPicker →
workspace.md, skills/* events → skills.md, and the four launcher-provided tui
accessor values join the named exemptions.

 `HttpServerService`（`ctx.httpServer`）在激活时立即监听；监听失败（EADDRINUSE 等）会从 init 抛出，形成一个 FAILED fiber，由启动的大声失败 sweep 上报。`register(route)` 添加一条具名路由并返回其 disposer；重复的 `(kind, path)` 抛出异常，因为路由模式是组合层契约，冲突即配置错误。`tapIndex(transform)` 添加一个纯的 html 到 html 转换，按注册顺序应用于每个 index 响应（`/` 和每次 SPA 回退）；[dsh-client-modules](../../packages/client/modules) 用它注入启动 manifest（元数据清单）。`port` 读取监听端口，`config.port` 为 0 时读到的是操作系统分配的值。
 
 处理过程中抛出异常的请求（畸形的 % 转义撞上 `decodeURIComponent`、客户端在请求体中途断开）会记录为警告并应答 400（响应头已发出时则销毁 socket），绝不导致进程退出。dispose（资源释放）把 `close()` 与 `closeAllConnections()` 配对使用，因为处理器可能像 SSE（Server-Sent Events）那样保持响应打开，而这类连接永远不会自行结束；没有强制关闭，拆卸就会挂起。该包（package）从不打印输出：URL 行归 shell 所有。逐包运维细节（含开发模式的 bundle 监视流水线）留在 [README](../../packages/host/webserver/README.md) 中。

+## Cordis surface
+
+Generated from source by `scripts/gen-cordis-catalog.ts` (verified fresh by `pnpm run verify-cordis-catalog` in doc-sync; regenerate with `pnpm run gen-cordis-catalog`) — this section is byte-identical in both language sides of the page. Signature blocks use a `ts cordis-catalog` fence and keep the original source JSDoc; dispatch modes are defined in the [primer](../cordis-primer.md#dispatch-modes), and the framework-inherited `ctx` surface lives in [cordis-api/inherited.md](../cordis-api/inherited.md).

+### `ctx.httpServer` — `HttpServerService`
+
+The web-shape HTTP carrier service. Activation listens immediately (route registration order carries no request-facing semantics: named routes are composed to be disjoint, and the fallback seat answers anything not yet claimed during the boot window — 404 until its owner registers). A listen failure throws out of init — a FAILED fiber the boot's fail-loud sweep reports.

+ * Register a named route. Duplicate (kind, path) throws — route patterns are
+ * a composition-level contract, so a collision is a misconfiguration.

+ * @returns the disposer removing the route.
+ */
